New technology turns plastic waste into oil


Новая технология превратит пластиковые отходы в нефтьAs a result of processing will produce many valuable products.

Every year the world produces millions of tons of plastic products, which are then transformed into waste. So, as of 2015 the year to 12.7 million metric tons of plastic debris each year falls into the oceans. What if we turn these giant gyre of plastic in the fuel?

Scientists at Purdue University (USA) led by Professor of chemistry Linda Wang has developed a technology of processing of the polyolefin, the most common type of thermoplastic used in the creation of a variety of products – from bottle caps to scientific instruments.

According to her, the result of processing will produce many valuable products, including polymers, naphtha (mixture of hydrocarbons) and various types of fuel.

Linda Wang and her colleagues turned to a technology called “hydrothermal liquefaction”. It consists in heating the materials to moderate temperatures under high pressure, which turns them into oil, consisting of plenty of valuable hydrocarbon compounds. Thus, scientists have learned to process up to 91% of the polyolefin.

The resulting oil is then transformed into gasoline mixtures and raw materials for other chemicals, which can also be divided into different types of fuel, in particular gasoline and diesel fuel. In quantitative terms, their production can be increased to 4% of global consumption.
